Best answer
The correct option is (b) Magnesium

Explanation: Out of the four metals given, magnesium will readily lose electrons due to its relatively higher reactivity. Copper and iron are not affected by gaseous or liquid chlorine. Lastly, aluminum forms a tough, passive oxide layer which prevents it from reacting with external reagents.
